Switch positions are binary coded. Key 4 ----- ON Enable OFF Disable This drive supports the tag 4/5 functions. The user can select these functions by setting Key 4. In the OFF position tag 4/5 are disabled. Control units that do not support tag 4/5 require this set to OFF. Key 5 ----- ON Enable write protection OFF Disable write protection Key 6 ----- OFF Set device type to M2372K This key will always be OFF. Tag 4/5 feature must be enabled to obtain device type status. Key 7 ----- ON Variable Soft sector mode OFF Hard Sector mode The user can select either hard sector or soft sector mode. In the case of Hard Sector, the number of sectors per disk revolution must be set. Terminal SW2 Main PCA --------------------- Key 1 ----- ON Calibration seek performed OFF Normal Calibration seek must be executed at any time the main PCA is replaced to optimise the servo control coefficient. To execute the calibration seek set key 1 to the ON position and turn on the power. Calibration seek is performed automatically. After completion, the ST0 LED will blink. Set key 1 to the OFF position to put the drive in the READY state. Key 2 ----- OFF Not used Key 3 ----- ON Vertical mounting (on side) OFF Horizontal mounting This key adjusts the servo characteristics that depend on the orientation of the drive. NOTE: A wrong setting may cause seek or write offtrack errors.
